Hi. I'm a Pearl Jam fan (hence the name, ) and I was wondering what a certain bass Jeff Ament plays. On a certain fan site it says it is a Fender Jaguar/Jazzmaster bass. I've never seen one of these before. Unfortunatly I don't have a pic of the headstock. Don't be put off by the pickups, he has all of his basses customised with Bartolini. Thanks for any help.
